An annual favorite that I very much look forward to unveiling every year, this is the new Harry Winston Histoire de Tourbillon, No. 8. As with last year color variations are being made, limited to 10 pieces each. Harry Winston’s “Histoire de Tourbillon” is of course a collection of limited edition timepieces in which Harry Winston pays its tribute to one of the most revered and complex horological complications. The first Histoire de Tourbillon debuted in 2009, with new interpretations released annually. All the pieces are fairly dramatic and/or otherwise spectacular in their design, utilizing inclined multi-axial, and/or the linking of multiple tourbillons.
This year’s Histore de Tourbillon 8 is no different in its splendor, and again features two-biaxial tourbillons (as with last year’s #7), unified by a spherical differential. Wrap your head around that! Naturally, the two large tourbillon cages feature prominently on the dial where they perform their slow, precise ballet.
Full breakdown, below.
Harry Winston Histoire De Tourbillon 8 Watch
Limited edition 20 piece: 10 in anthracite, 10 in dark grey + red accents
51mm x 17.3mm white gold case, fitted on hand-stitched alligator leather strap with red or black needlework that matches the color of the watch dial
The 51mm white gold case features alternating polished mirror and satin finishes that highlight its various details, such as the three Harry Winston arches located at 3 and 9 o’clock, respectively. The dial’s entire surface area is actually one component, made up of 13 different elements with varying textures and finishes (sanded, grained, satin, honeycomb patterns). The two conical discs, housing the hour and minute displays, are made of aluminum.
The HW4503 caliber measures in at a whopping 43mm in diameter and is equipped with two rapidly rotating superposed barrels, one of which is equipped with a slipping spring, which Harry Winston notes results in “no sensation of disruption when winding the barrels.” and neutralizing the the possibility of applying too much tension by overwinding. Its plates and bridges are also made of titanium.Within the latter, the balance wheel keeps the tempo at a frequency of 21,600 vibrations per hour.
Comprised of 117 components, each biaxial tourbillon weighs no more than 0.76 grams thanks in part to titaniun construction. Each of their two regulating movements operate independently, but are linked via a spherical differential so as to derive a unified time measurement. Every 75 seconds, each tourbillon completes a rotation on a 30-degree inclined axis. Nested within this movement, a second cage turns on its own axis, completing a rotation every 45 seconds.
